If applied force is at an angle to motion, how can you find the force that is causing the motion?
a triangle! trig!
Ignoring friction, for systems like an object thrown straight up, dropped straight down, or a pendulum, what is true of the mechanical energy of the system over time? (until landing!)
should stay the same, but converts from potential to kinetic and back again
